|Shareholders' Equity and Capital Stock||
In 2005, the Company’s Board of Directors approved the adoption of the Company's stock option plan (the “Option Plan”). The Option Plan was most recently approved by the shareholders, including certain amendments, on May 18, 2017. Eligible participants under the Option Plan include directors, officers, employees and consultants of the Company. Under the terms of the Option Plan, stock options granted prior to the May 2017 amendment generally vest with Option Plan participants as follows: 10% at the date of grant; 22% four and one-half months after grant; 22% nine months after grant; 22% thirteen and one-half months after grant; and the balance of 24% eighteen months after the date of grant. Following the May 2017 amendment of the Option Plan, future grants of options will vest over a three-year period: 33.3% on the first anniversary, 33.3% on the second anniversary, and 33.4% on the third anniversary of the grant. The term of options remains unchanged.
Activity with respect to stock options is summarized as follows:
The exercise price of a new grant is set at the closing price for the shares on the Toronto Stock Exchange (TSX) on the trading day immediately preceding the grant date so there is no intrinsic value as of the date of grant. The fair value of options vested during the six months ended June 30, 2017 was $0.2 million.
As of June 30, 2017, outstanding stock options are as follows:
The aggregate intrinsic value of the options in the preceding table represents the total pre-tax intrinsic value for stock options with an exercise price less than the Company’s TSX closing stock price of Cdn$0.82 as of the last trading day in the period ended June 30, 2017, that would have been received by the option holders had they exercised their options as of that date. The total number of in-the-money stock options outstanding as of June 30, 2017 was 5,289,303. The total number of in-the-money stock options exercisable as of June 30, 2017 was 3,353,402.
We elect to estimate the number of awards expected to vest in lieu of accounting for forteitures when they occur.
Restricted share units
On June 24, 2010, the Company’s shareholders approved the adoption of the Company’s restricted share unit plan (the “RSU Plan”). The RSU Plan was approved by our shareholders most recently on May 5, 2016.
Eligible participants under the RSU Plan include directors and employees of the Company. RSUs in a grant redeem on the second anniversary of the grant.
Activity with respect to RSUs is summarized as follows:
As of June 30, 2017, outstanding RSUs are as follows:
Upon RSU vesting, the holder of an RSU will receive one common share, for no additional consideration, for each RSU held.
The following represents warrant activity during the period ended June 30, 2017.
As of June 30, 2017, outstanding warrants are as follows:
Share-based compensation expense
Share-based compensation expense was $0.4 million and $0.7 million, respectively, for the three and six months ended June 30, 2017 and $0.2 million and $0.4 million for the three and six months ended June 30, 2016, respectively.
As of June 30, 2017, there was approximately $0.6 million of total unrecognized compensation expense (net of estimated pre-vesting forfeitures) related to unvested share-based compensation arrangements granted under the Option Plan and $0.4 million under the RSU Plan. The expenses are expected to be recognized over a weighted-average period of 1.2 years and 1.5 years, respectively.
Cash received from stock options exercised during the three and six months ended June 30, 2017 totalled $NIL and $0.3 million, respectively, and less than $0.1 million for the three and six months ended June 30, 2016.
Fair value calculations
The initial fair value of options and RSUs granted is determined using the Black-Scholes option pricing model for options and the intrinsic pricing model for RSUs. There were no RSUs granted in either the six months ended June 30, 2017 or the six months ended June 30, 2016 nor were there any options granted in the six months ended June 30, 2016. The assumptions used for the options granted during the six months ended June 30, 2017 were as follows:
The Company estimates expected volatility using daily historical trading data of the Company’s Common Shares, because this is recognized as a valid method used to predict future volatility. The risk-free interest rates are determined by reference to Canadian Treasury Note constant maturities that approximate the expected option term. The Company has never paid dividends and currently has no plans to do so.
Share-based compensation expense is recognized net of estimated pre-vesting forfeitures, which results in recognition of expense on options that are ultimately expected to vest over the expected option term. Forfeitures were estimated using actual historical forfeiture experience.
The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.
